As the era of ubiquitous computing unfolds, interactive systems are nowadays becoming intelligent and able to develop their intentionality. While tangible interfaces are usually exploited to manipulate systems with various degrees of control, the expression of these tangible interfaces, as well as the coupling of both, remain underexplored. By explorations, this paper finds most peripheral interaction designs heavily rely on tangible interfaces, addressing either the peripheralness of the system’s output or user’s control. Consequently, this paper synthesizes the attributes of variants of interfaces and correspondingly illustrates three tangible interfaces that couple both system’s output and user’s control. This might provide future researchers and designers hints on how user control and the system can be tangibly incorporated.
